New Hampshire State Flower: Purple Lilac
Fact-checked • Updated December 10, 2025
New Hampshire State Flower – Purple Lilac
New Hampshire designated the Purple Lilac as its official state flower in 1919. These fragrant purple flower clusters bloom on shrubs throughout New Hampshire. Sweet scent fills New Hampshire neighborhoods each May when thousands of lilac bushes burst into bloom.
What Is the New Hampshire State Flower?
New Hampshire officially recognizes the Purple Lilac as its state flower. Each flower cluster contains dozens of tiny tubular blooms. Purple petals range from light lavender to deep violet. The flower heads measure 4 to 8 inches long. A powerful sweet fragrance attracts bees and butterflies. Single flowers measure about a quarter inch across.
Purple Lilacs bloom from late April through May across New Hampshire. Southern regions see earlier blooms than northern areas. Peak flowering lasts about two weeks. Individual flowers remain fresh for several days. The shrubs grow 8 to 15 feet tall. Heart-shaped leaves appear dark green. Multiple stems branch from the base forming dense thickets.
Lilac bushes thrive throughout New Hampshire in gardens and along roadsides. The shrubs tolerate cold New Hampshire winters. Well-drained soil suits lilacs best. Full sun produces the most abundant blooms. Old farmhouse foundations often feature ancient lilac bushes. These hardy shrubs can survive decades of neglect and still produce flowers each spring.
New Hampshire State Flower Name
This flower carries the common name Purple Lilac and the scientific name Syringa vulgaris. The plant belongs to the Oleaceae family. This family includes olives, ash trees, jasmine, and about 600 other species worldwide.
The genus name Syringa comes from the Greek word for tube. It describes the hollow stems. The species name vulgaris means common in Latin. Common lilac serves as another name for this species. The plant originated in southeastern Europe. Colonists brought lilacs to New England in the 1750s.
New Hampshire specifically designated the purple variety rather than white or pink lilacs. Purple blooms were most common in New Hampshire gardens. The distinctive color made identification easy. White lilacs belong to the same species but produce different colored flowers. Some confusion exists because mock orange shrubs sometimes get called syringa despite being unrelated plants.
Why the Purple Lilac Became the New Hampshire State Flower
New Hampshire proclaimed the Purple Lilac its official state flower in 1919. The state legislature made this choice following advocacy by garden clubs. Women's organizations throughout New Hampshire promoted the lilac selection. School children participated in discussions about state symbols.
Lilacs grew abundantly in New Hampshire gardens and dooryards. Old farmhouses featured lilac bushes planted by early settlers. The purple blooms symbolized spring and renewal after harsh winters. Their sweet fragrance represented New Hampshire hospitality. Hardy shrubs survived New England's difficult climate without special care.
Some people suggested native wildflowers like lady's slipper or trailing arbutus instead. Supporters of the lilac argued that immigrant plants had become part of New Hampshire's heritage. Lilacs bloomed reliably every spring across the state. The legislature agreed and passed the designation on March 28, 1919. New Hampshire joined other states adopting state flowers during this period.
